EMIL DIEIBOLD, OF ENNETBADEN, SWITZERLAND.

PLAITING-MACHINE.

To all whom, it may concern Be it known that I, EMIL DIEBOLD, a citi zen of the Republic of Switzerland, residing at Ennetbaden, in the Canton of Aargau, Republic of Switzerland, (whose postoffice address is Ennetbadem) have invented a certain new and useful Improved Plaiting- Machine; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to plaiting machines and more particularly to the mechanism for transferring the bobbin spindles from one driver to another in such machines.

The object of the invention is to provide improvements in such spindle mechanisms whereby the necessary driving power will be reduced to a minimum and the wear of the parts greatly limited, while at the same time the revolutions and production of the machine may be appreciably increased.

A further advantage of my improved plaiting machine is that the guide plates and pointers for the control of the bobbin spindles hitherto adopted in plaiting machines are eliminated which greatly simplifies and cheapens their manufacture.

The most prominent features of my present invention reside in means for preventing the bobbin spindles from dropping off from the driving wheels by which they are carried, and means for preventing the rotation of the spindles on the said driving wheels, for the purpose hereinafter described in detail.

Several examples of my improved plaiting machine are given in the accompanying drawings, those parts necessary for the explanation of the invention alone being illustrated.

Figure 1 shows a plan and Fig. 2 an elevation of one constructional form of the spindle guide arrangement. Fig. 3 is an elevation of the whole machine. Fig. 1 is a plan of a second construction of the spindle guide mechanism. Fig. 5 is an elevation of a part of Fig. 1, on a larger'scale.

shaft 5 1 which drives a horizontal shaft 57 through a worm 55 and a worm wheel 56. From the horizontal shaft a shaft 62 is driven through rope pulleys 58 and 59 and a rope 60. On the latter shaft is mounted a drum 61 on which is wound up the plaitecl work made by the machine.

A number of vertical bolts 65 are fastened with the aid of plates 63 on a plate 62* of the machine frame and on each bolt is loosely mounted a sleeve 66" carrying a toothed wheel 67. The toothed wheels on the various bolts are all in mutual engagement and one of them gears with a toothed wheel 68 keyed on a shaft 541 so that on rotation of this shaft all the toothed wheels are driven. On each tube 66 are mounted two driving wheels 1 1 or 2 2 having recesses 6 for the bobbin spindle. Each driving wheel is provided with holders 7 in the form of pins each being located near one of the recesses and on a radius passing through a recess.

Each bobbin spindle carries a counter holder 8 consisting of a ring with two lateral oppositely curved lugs 8 and 8 the latterbeing so arranged that when a spindle is in a recess in the driver as shown in Fig. 1, one or both lugsof the counter holder are below their corresponding pins 7 and thus prevent the bobbin spindle from falling out of its seat without previous rotation of this latter.

To prevent undesired rotation of the spindle on their supporting driving wheels, a nut 9 is mounted on the spindle tube with two pairs of checks-10 10 and 11 '11 which are milled on the faces opposite the driving wheels so as to be concentric to these latter; the cheeks 10 10 are situated slightly lower than the cheeks 11 11".

. Concentric to the driving wheels, but fixed, are disk-shaped guides or plates 12 and 13 which are formed on the sides facing each other with recesses 12 and 13, the recess 12 being on the upper side of the plate 12 and the recess 13 on the lower side of the 'plate 13.

The operation of this spindle guide mechanism during the working of the machine will now be described; the actual plaiting not being a feature of the invention, is not explained.

The driving wheels are assumed to have. the rotations in the directions denoted by arrows in Fig. 1, and the bobbin spindle 4 still on the driving wheel 2 is just about to be transferred to the driving wheel 1. In this position in the case of the bobbin spindle 4 the cheek 10 is in contact with the plate 12 and thereby prevents the bobbin spindle with the driving wheel 2 from further rotation about its center of rotation. The check 10", however, lies opposite the recess 13 and makes it possible for the bobbin spindle 4 with the driving wheel 1 to rotate about its center of rotation, whereupon the cheek 10" moves through the recess 13. The pin 7 of the driving wheel 2 slides off the lug 8 of the bobbin spindle 4 and on its continued motion by the pin 7 of the driver 1, the bobbin spindle is prevented from being impelled away by means of the contact of the lug 8. A throwing off of the bobbin spindle would be possible only when the same can rotate about its own axis in the recess in the driver, which however is prevented by the cheeks 10 and 11. In the same manner an undesired removal of the bobbin spindle 3 from the driver 1 is impossible. WVhen the bobbin spindle 3 arrives at the place of the bobbin spindle 4, the lower cheek 10 moves freely through the recess 13 of the fixed plate 13, while the upper cheek 11 encounters the full upper edge of the plate 18 and thus prevents the bobbin spindle 3 from further motion with the driver 1. Meanwhile, the bobbin spindle 3 has also entered the corresponding recess in the driver 2; a recess 12 in the plate 12 enables the bobbin spindle 3 with the driver 2 to move about its center of rotation. In this direction of motion of the bobbin spindle also the corresponding pin 7 along with the lug 8 prevents the throwing off of the bobbin spindle, and the cheeks 10 and 11 the rotation .of these latter. When the direction of motion of the bobbin spindles is that of the spindle 4 the upper cheeks l1 and 11 move outward, but when it is that of the bobbin spindle 3 the lower cheeks 10 10 move outward. This is the case when all the spindles describe a closed path around the center of plaiting, as in round plaiting machines.

There are some plaiting machines in which the plaiting path is not closed, such a case being shown in Fig. 4. In machines of this type the driving wheels at the ends of the plaiting path are of somewhat larger diameter than the others in order that an additional recess may be provided on them while retaining the same pitch between the recesses as in the other drivers. My improved spindle guide mechanism is equally applicable to machines of this type, as shown by way of example in Figs. 4 and 5. Priorto describing the operation of the spindle guide mechanism it should be explained that in the case of the left hand end driver 1, for example, the bobbin spindles enter the said driver in the direction of the arrow I and travel away from it in the direction of the arrow II. As in the case of Fig. 1 when the bobbin spindles are transferred from left to right from one driver to the other (arrow II) the upper cheeks of the bobbin spindle move in advance. It is assumed that the bobbin spindles are transferred from the two last drivers to the end driver in the direction of the arrow I. As in this latter, however, as shown by Fig. 4, the lower cheeks move outward, they must be rotated through 180 during one revolution of the spindle in order that they may again move away from the left hand end driver in the direction of the arrow II. To this end an upright rod 14 is arranged on the machine frame and provided with a pin 15 projecting into the path of the lug 8. The rod also carries a guide plate 16 which partially surrounds the driver 1, and a striker 17 projecting into the path of the cheeks 10 and 10". When the driver 1 is rotating in the direction indicated the h1g8 strikes against the pin 15 and partially rotates the bobbin spindle after which the cheek 10 encounters the striker 17 which causes a further rotation of the bobbin spindle whereby the latter is brought into the position in which undisturbed transference can take place, the pin 7 being in front of the lug 8; in order that rotation of the bobbin spindle may take place the plates are provided with suitable recesses. The purpose of the plate 16 is to prevent the throwing off of the bobbin spindles in those positions in which the pin 7 is out of engagement with the lugs. 18 denotes a further striker mounted on the plate 16, cotiperating with the cheeks 11 and 11, which striker only comes into use when the machine is operating in the reverse direction to that illustrated. Also those bobbin spindles leaving the right hand end driver 2 must rotate about their own axes during their course, for which purpose a pin 19, a plate 20, and strikers 21, 22 are provided.

In the production of certain plaitings it may happen that one bobbin spindle as an except-ion should not be transferred from one driver to the other. This result may be attained by making the cheeks in question ineffective, in any suitable manner before the instant of transference. In Figs. 6 and 7 an example of this kind is illustrated. On the spindle tube 35 is fixedly mounted a sleeve 36 over which a second sleeve 37 is loosely mounted; the latter has a curved groove 38 with which cooperates a pin 39 bent down at the top and displaceably guided in the sleeve; this pin carries at its lower end a plate 40 on which are formed the two cheeks 11 and 11 and there is a spring 41 on the top abutting against the sleeve 36, which spring tends to press the plate downward. The spindle just described is used in connection with the driving wheel illustrated in Figs. 1 and 2. When the plate 40 is depressed the cheeks 11, 11 lie in the same position as the corresponding cheeks in Figs. 1 and 2 and the bobbin spindle operates in the same manner as in that example. lVhen, however, the plate 40 is lifted up by the rotation of the sleeve 37 the cheeks 11, 11' are removed from the operative influence of the plate whereby the bobbin spindle in this case is not transferred from one driver to the other at the places of contact of the drivers. The rotation of the sleeve 37 is effected at the proper time by the striking of a pin 42 on the said sleeve against a fixed striker not illustrated.

In the construction after Figs. 8 and 9 the plates 12 and 13 are provided on the sides facing each other with recesses 12 and 13 extending over their entire height which recesses are normally covered by flaps 43, 44, hinged on the respective plate; springs 45 and 46 coiled about a guide pin press these flaps in the lowered position. The flaps are each provided at one end with a projection 47 having an oblique surface. Each bobbin spindle possesses two diametrically opposite pins 49 and 49 one of which on the trans ference of the bobbin spindle to the adjacent driver cOmes into contact with the corresponding flap. The bobbin spindles resemble those of Figs. 1 and 2 with the exception that all four cheeks are arranged at the same height. It is assumed that the driving wheels rotate in the direction of the arrows in Fig. 8, and the bobbin spindle is being transferred from driver 2 to driver 1. In the position illustrated the pin 49" is underneath the flap 44 holding it in raised position while the flap 43 remains lowered. The pin 49 is not in contact with the flap 43, the oblique surface 47 being too far from the edge of-the driver 13. It may be seen from Figs. 8 and 9 that the flap 43 owing to the contact of the cheeks 10 and 11, prevents further rotation of the bobbin spindle with the driver 2. The raised flap 44 enables, however, the transference of the bobbin spindle to driver 1 to take place, the flap 44 being lifted above the cheeks 10", 11 by the pin 49". The raising of the flap 44 is caused by the pin 49, whlch, when the bobbin spindle moving with the driver 13 ap proaches the illustrated position, moves under the oblique surface 48 and raises the flap. From the foregoing description it is easy to understand the method of operation also for the case in which the bobbin spindle is to be transferred from the driver 1 to the driver 2.

In the example illustrated in Figs. 10 and 11, and 71 denote the driving wheels revolving on the fixed pin 72, 73. Each spindle is mounted in a holder 74 which is provided at the bottom with an edge 75 and is prevented from upward displacement by means of grooves in the drivers 70 and 71. Each driver is provided with upwardly directed pins 76 arranged adjacent to the recesses for the reception of the spindle holders, while the spindle holders have downwardly directed lugs 77 adapted to cooperate with the pins 76. As in the previously described examples there are two upper and two lower cheeks 78, 78 and 79, 79, the cheeks 78, 79 and the lugs 77 being in one piece. The operation is the same as in the example after Figs 1 and 2.

What I claim is 1. In a plaiting machine, the combination of a plurality of driving wheels, recesses therein for the reception of the bobbin spindles, lugs on these spindles, pins on the driving wheels located adjacent to the recesses which pins prevent the dropping of the spindles owing to their contact with the lugs, fixed guide plates, and two pairs of cheeks on the spindles which cheeks are in contact with the guide plates and prevent a rotation of the spindles on the driving wheel.
